The major satisfaction of college students will influence their learning interest and motivation, and then influence their learning achievement and future employment. Under the guidance of the concept of the micro system engineering of the education reform, the degree of the major satis-faction of the students in TCM colleges is analyzed by SIMPP method. The results show that students' behavior mode such as their preview situation, teaching adaptation, course satisfaction, students' achievement and their attitude of poor academic performance is closely related to the degree of major satisfaction. Teachers can judge the degree of major satisfaction by following these pattern behaviors;improve the rationality and accuracy of the degree of major satisfaction.

The influence extent of students from teachers is related to the teaching effect , which means whether it can successfully promote the study of students and reach the expected teach-ing goal during the teaching process. To have a good teaching effect, guided by the micro-system en-gineering of teaching reform, we used SIMPP to analyze the related factors of the influence of students extent from teachers during the teaching process in TCM colleges and universities. The result shows that the influence extent from teachers is related to not only teachers themselves but students and their self-condition and family backgrounds as well. Going further in researching these factors and the related behavior patterns of influence extent of students from teachers is helpful to making the teach-ing more effective and more targeted.

The prescription combinations of traditional Chinese medicine (TCM) focuses on the taste and channel tropism, the Qi movement, as well as the compatibility according to multiple combination principles and medicinal property and flavor combination of several traditional Chinese medicines. With the in-depth study on the prescription compatibility, researchers have realized that the medicinal property theory is the core of TCM combinations. However, there is no definite method for combinations based on medicinal properties. In this paper, the authors put forward an method for designing prescription combinations based on bipartite graph and the greedy algorithm. With the medicinal property combinations of Siweilurong Pills for example, the authors proved this method could provide ideas for quickly choosing herbal medicines for prescription combinations, and discussed the prospect of this method in substituting previous and endangered herbal medicines and banned medicinal materials.

Optimization of sensor array is a significant topic in the application of electronic nose (EN). Stepwise discriminant analysis and cluster analysis combining with screening of typical index were employed to optimize the original array in the classification of 100 samples from 10 kinds of traditional Chinese medicine based on alpha-FOX3000 EN. And the identification ability was evaluated by three algorithm including principle component analysis, Fisher discriminant analysis and random forest. The results showed that the identification ability of EN was improved since not only the effective information was maintained but also the redundant one was eliminated by the optimized array. The optimized method was eventually established, it was accurate and efficient. And the optimized array was built up, that is, S1, S2, S5, S6, S8, S12.

Objective To analyze effects of different temperatures of postoperative rinse solution on rehabilitation of patients underwent transurethral resection of prostate (TURP), and to select the optimal temperature of postoperative rinse solution. Methods A total of 150 cases were divided into 5 groups at random,30 cases per group. Temperatures of postoperative rinse solution of each group were 25 ℃, 28 ℃, 31 ℃, 34 ℃, 37 ℃ separately, then body temperature, incidence rate of cyst spasm , the difference of HB concentration between pre-rinse and post-rinse,and average stay postoperatively of each group were contrasted. Results Incidence rate of low body temperature and cyst spasm fall off gradually with increase of temperature of rinse solution; average stay of the group( 34 ℃ ) was shorter than the groups( 25 ℃ ,28 ℃ ,31 ℃ ), which had statistical significance( P < 0.05 ) ; Compared with the other groups, the difference of HB concentration between pre-rinse and post-rinse of the group (34 ℃ ) had statistical significance( P < 0.05 ). Conclusions The optimal temperature of postoperative rinse solution is 34 ℃.

OBJECTIVETo explore the relationship between G2139A,G3091A, T663A, and T3593C single nucleotide polymorphisms (SNPs), which are located at the promoter region,13th exon, and 2nd intron of epithelial sodium channel (ENaC) gene, and their haplotypes with essential hypertension (EH) in Kazakhs in Xinjiang.

METHODSA case-control study was conducted including 252 EH patients (EH group) and 254 normotensive subjects (NT group) among Kazakhs in Xinjiang. The four genetic polymorphisms were identified by polymerase chain reaction - restriction fragment length polymorphism. The distribution of the genotypes and alleles in all subjects and the different frequency of these four SNPs between EH group and NT group were analyzed. The linkage disequilibrium and haplotypes of these four SNPs were analyzed.

RESULTSThese four SNPs of alpha ENaC gene existed in Xinjiang Kazakhs. In all subjects, the distribution frequencies of genotypes AA, AG, and GG at G2139A were 26.2%, 52.3%, and 21.5%, respectively, and those of alleles (A, G) were 52.37% and 47.63%. The distribution frequencies of genotypes AA, AG, and GG at G3091A were 19.0%, 52.5%, and 28.5%, respectively, and those of and alleles (A, G) were 45.56% and 59.44%. The distribution frequencies of genotypes AA, AG, and GG at T663A were 15.6%, 49.9%, and 34.5%, respectively, and those of alleles (A, G) were 40.53% and 59.47%. The distribution frequencies of genotypes TT, TC, and CC at T3593C were 88.5%, 10.5%, and 1.0%, respectively, and those of alleles (T, C) were 93.77% and 6.23%. The distribution of genotypes at these four SNPs were all consistent with Hardy-Weinberg equilibrium in this population (P0.05). The distribution frequencies of genotypes and alleles about these four genetic polymorphisms were not significantly different between the EH group and NT group (P0.05). However, the frequencies of two haplotypes were found to be significantly different between these two groups (P0.05). The haplotype frequency which included 2139G, 3091A, 663G, and 3593T alleles was significantly increased in EH group (P0.01), while the haplotype frequency which included 2139A, 3091A, 663A, and 3593C alleles was significantly increased in NT group (P0.05).

CONCLUSIONSThe haplotypes that are composed of G2139A, G3091A, T663A, and T3593C polymorphisms of alphaENaC gene may play an important role in the development of EH among Kazakhs in Xinjiang. The haplotypes that are composed of 2139G, 3091A, 663G, and 3593T alleles may aggravate the development of EH. The haplotypes that composed of 2139A, 3091A, 663A, and 3593C alleles may decrease the risk of EH among Kazakhs.
